Abstract

Agricultural field especially in the cultivation of crops, soil conditions and management are important factor that will determine the growth and yield of crops cultivated. In Indonesia, the Ultisols are generally not well handled. On a large scale, the land of Ultisols has been utilized for oil palm plantations, rubber and industrial crop forests, but on the scale of farmer economic constraints is one of the causes of unmanaged soil is well. The province that has a Ultisols spread very widely is East Kalimantan 10.04 million ha, west Kalimantan 5.71 million ha, central Kalimantan 4.81 million ha and Riau 2.27 million ha. The problem faced is the limitation of fertile land and lack of information about the condition of land, to increase production of oil palm in the village Tebedak District Ngabang Regency Landak, it is necessary to study some properties of soil chemistry So that from this research can provide fertilizing advice.This research aims to study some of the chemical properties of the Ultisols soil which are planted with palm oil in several gardens and suggested of Nitrogen, phosphorus and Potassium in village Tebedak District Ngabang Regency Landak. This research is expected to provide information on chemical properties of soil in village Tebedak District Ngabang Regency Landak. The parameters in this study is the reaction of the soil (pH), organic carbon, total nitrogen, phosphorus and potassium available, interchangeable, calcium, magnesium can be exchanged, cation exchange capacity, base saturation, soil texture, and bulk density.The taking of soil samples taken at Palm Gardens in the village Tebedak District Ngabang Regency Landak, soil samples were taken at 5 different Palm locations, each location taken 5 point diagonally and made the composite sample of 1 so that composite samples obtained 5 were analyzed in the laboratory of chemistry and soil fertility Faculty of Agriculture University of Tanjungpura.

Abstract

Peatland in Indonesia has a potential for maize cultivation, but it has constraints that low of soil pH and of nutrient availability. Use of ameliorants from coastal sediment and salted fish waste was an alternative to improve peatlands productivity and maize yields. Objective of the study was to examine effects of coastal sediment and salted fish waste on growth and yield of maize at three kinds of soil of peatlands of Kubu Raya, West Kalimantan. This research was conducted  in  field  using  Inter-area analysis  design.  The  first  factor  was  combination  of  each ameliorants  which consisted of 5 levels, namely: 1) treatment under farmer custom at the sites (control); 2) coastal sediment of 20 Mg ha-1 + 0.75 Mg of salted fish waste ha-1; 3) coastal sediment of 40 Mg ha-1 + 1.5 Mg of salted fish waste ha-1, 4) coastal sediment of 60 Mg ha-1 + 2.25 Mg of salted fish waste  ha-1. The second factor was soil types which consisted of three levels, namely: Typic Haplohemists, Typic Sulfisaprists and Typic Haplosaprists. Each treatment was repeated 5 times. The results showed that combination of 40 Mg ha-1 of coastal sediment and 1.5 Mg ha-1 of salted fish waste was the best combination for all soil type. It increased plant height (33% - 44%), shoot dry weight (74% - 75%), number of seeds per cob (31% -110%), weight of 100 seeds (58% -71%) and dry grain weight per plant (136 % -160 %) at each soil. The highest yield was found in soil of Typic Haplosaprists (219.54 g), followed by Typic Sulfisaprists (210.72 g) and Typic Haplohemists (208.82 g).Keywords: Coastal sediment, maize, peat soils, salted fish waste [How to Cite: Denah S, BH Sunarminto, D Shiddieq and D Indradewa. 2014.

Abstract

The application of ameliorant has been suggested to improve soil fertility and crop growth in post illegal gold mining (PIGM) lands. This study evaluated the effect of ameliorant types and semi-permeable layer on properties of soil in PIGM lands and growth of sorghum. A field experiment employed two treatments, i.e. type of ameliorant and semi-permeable layer. There were four ameliorant types applied i.e., without ameliorant (M0); coastal sediment at a dose of 40 t/ha (M1); biochar at a dose of 4 t/ha (M2), and coastal sediment at a dose  of 30 t/ha + 4 t biochar/ha(M3).  The second treatment consisted of two levels, namely: without a semi-permeable layer (S0) and the semi-permeable layer of 20 cm depth from the soil surface (S1). The results showed that types of ameliorant gave different effect to soil properties. Application of coastal sediment at a dose of 40 t/ha significantly increased the contents of Ca and Mg, whereas application of biochar at a doses of 4 t/ha increased soil CEC. The semi-permeable layer did not significantly affect plant height and stem diameter of sorghum. The highest of sorghum growth was reached by application of coastal sediment at a dose of 30 t/h + biochar at a dose of 4 t/ha. The combination of coastal sediment and biochar from banana peels could complement each other to improve soil fertility in PIGM land

Abstract

Cadmium (Cd) is a heavy metal that can contaminate agricultural soils, in which one of the sources of Cd in agricultural soils is the use of phosphate fertilizers. Some plant species are known to have the ability to accumulate large amounts of Cd in their organs despite the Cd content in soil is relatively small. Cadmium distribution in various organs of plants also shows a diverse variation. Maize is able to accumulate Cd in its organs, either in roots, leaves or grains. This study aims to determine the distribution of Cd in sweet corn plants grown on a peat soil. Samples of maize plants were taken from nine maize fields in the village of Rasau Jaya 1, Rasau Jaya subdistrict, Kubu Raya district, West Kalimantan. The cultivars of sweet corn planted were Zea mays saccharata cultivar Bonanza and Zea mays saccharata cultivar Secada. Samples for roots, leaves, stems and panicles were taken at the stage of early grain filling. Grain samples were taken at the phase of fresh pod consumption. The Cd contents in the plant organ tissues were determined using dry ashing method. The  results showed that the distribution of Cd in plant organs of sweet corn cultivars Secada and Bonanza follows the pattern of Cd in leaves > roots > grains > panicles > stems. The leaves contain the highest concentration of Cd, while the stems contain the lowest amount of Cd. The Cd concentration in leaves is about 3.5 times higher than that in grains, and 1.5 times higher than that in roots. The average Cd content in grains of sweet corn  is 0.037 mg kg-1, which is still below the safe limit of Cd content in grains allowed by the Standar Nasional Indonesia, i.e. 0.2 mg kg-1.

Abstract

ABSTRAKEffisiensi tanaman untuk fitoremediasi salah satunya ditentukan oleh besarnya akumulasi logam dalam biomassa tanaman yang dipanen. Akumulasi kadmium pada organ berbagai jenis tanaman menunjukkan respon yang beragam, Sebuah percobaan pot telah dilakukan pada 3 jenis tanaman famili Brassicaceae yaitu sawi hijau (Brassica rapa var. parachinensis ), sawi putih (Brassica rapa var. Pekinensis) dan kailan (Brassica oleracea var. Alboglabra) pada tanah gambut yang dikontaminasi kadmium (Cd) dengan tujuan mempelajari bioakumulasi Cd pada akar dan pucuk dari ketiga jenis tanaman tersebut dan menentukan jenis yang lebih potensial untuk fitoremediasi. Kontaminan Cd dicampurkan pada tanah dengan tingkatan dosis yang berbeda yaitu tanpa kontaminan, 2 mgkg-1 Cd, 4 mgkg-1 Cd, 8 mgkg-1 Cd, 16 mgkg-1 Cd dan 32 mgkg-1 Cd, dan tanah tersebut digunakan sebagai media tumbuh tanaman (5kg/polibag). Hasil penelitian menunjukkan kandungan Cd pada organ akar sawi hijau, sawi putih dan kailan lebih besar dari pucuk. Ketiga tanaman termasuk tanaman akumulator Cd. Kailan mempunyai kemampuan akumulasi Cd (BCF) yang lebih besar dari sawi hijau dan sawi putih, tetapi mempunyai kemampuan transfer Cd ke pucuk (TF) paling kecil. Sawi hijau dan sawi putih dengan biomassa yang besar dan mempunyai kemampuan transfer Cd ke pucuk yang jauh lebih besar dari kailan, lebih potensial digunakan untuk fitoremediasi tanah yang tercemar Cd.ABSTRACTPlant efficiency for phytoremediation depend on total amount of metal content in the harvestable tissues of plant biomass. Cadmium accumulation in the organs of various plant species showed varying responses. Field experiment was carried out with 3 crops of family Brassicaceae, i.e. Brassica rapa var. parachinensis, Brassica rapa var. Pekinensis and Brassica oleracea var. Alboglabra on Cd-contaminated peat soil. Contaminant Cd and soil were mixed in different dosages i.e. 2 mgkg-1 Cd, 4 mgkg-1 Cd, 8 mgkg-1 Cd, 16 mgkg-1 Cd and 32 mgkg-1 Cd and used to fill growth pot (5kg/pot).  The results showed that Cd accumulation in root of three crops tested greater than that in shoot. All of the three plants tested were characterized as Cd accumulator plant. Brassica oleracea var. Alboglabra was characterized by the highest Cd bioconcentration factor (BCF) and the lowest Cd shoot-root translocation factor (TF).  Brassica rapa var. Parachinensis showed highest biomass (>2 times biomass of Brassica oleracea var. Alboglabra) and highest Cd translocation factor may be suitable used for phytoremediation Cd contaminated soil.
